A recording medium device adapted so that a recording medium on which information signals are recorded is accommodated. This recording medium device comprises a cartridge body within which the recording medium on which information signals are recorded is accommodated, and an erroneous recording prevention member including a portion of detection detected by a detection mechanism of the recording/reproduction unit side, and attached to the cartridge body so that it can be moved within the range between a first position where the portion of detection is detected by the detection mechanism and a second position where it is not detected by the detection mechanism. This erroneous recording prevention member is attached to the cartridge body so that the portion of detection can be moved within the range between the first position and the second position by holding or clamping a portion of the cartridge body by a holding portion provided at the base end portion side where the portion of detection is provided and inserting an insertion portion provided at the front end side of the holding portion from the external side toward the internal side of the cartridge body.
